It appears that knfsd & knfsd-clients are replacing
nfs-server & nfs-server-clients. However not all the man
pages from the nfs* are included in knfs*. Specifically
exports(5) is not included.
PS. I hope this type of bug report is ok, as its not really
a huge issue, just more of an inconvenience.
fixed in knfsd-1.2-2
